Ultrafast enzyme immobilization over large-pore nanoscale mesoporous silica particles.
By finely tuning the TEOS/P123 molar ratio of the octane/water/P123/TEOS quadruple emulsion system and by controlling the synthesis conditions, an ultrafine emulsion system was isolated, under the confinement of which, nanoscale silica particles with ordered large mesopores (approximately 13 nm) have been successfully constructed; the obtained mesoporous silica particles have an unusual ultrafa...
متن کاملImmobilization of Enzymes on Nanoporous Silica Composites
Title of Dissertation: IMMOBILIZATION OF ENZYMES ON NANOPOROUS SILICA COMPOSITES Allan E. David, Ph.D., 2004 Dissertation Directed By: Associate Professor N.S. Wang, Department of Chemical Engineering Dr. A.J. Yang, ISTN, Inc. In this work, the sol-gel process is used to produce a chemically surface modified gel (CSMG) with a high modification density. Sodium silicate, an inexpensive alternativ...
متن کاملImmobilization of immunoglobulins on silica surfaces. Stability.
The development of new immunosensors based on surface-concentration-measuring devices requires a stable and reproducible immobilization of antibodies on well-characterized solid surfaces. We here report on the immobilization of immunoglobulin G (IgG) on chemically modified silica surfaces. Such surfaces may be used in various surface-oriented analytical methods. Reactive groups were introduced ...
متن کاملβ-Galactosidase Immobilization on Chitosan-Hydroxyapatite Complex: Effects of Immobilization Conditions
β-galactosidase simply known as lactase is a significant enzyme in food industry mainly used to hydrolyse lactose in milk. In addition to provide lactose free milk for lactose intolerant people, hydrolysis of lactose avoids textural problems in frozen milk products. β-galactaosidase from different sources has been immobilized on many various type of matrixes including chitosan, alginate, sepabe...
متن کاملImmobilization of folic acid on Eu3+-doped nanoporous silica spheres.
Folic acid (FA) was immobilized on Eu(3+)-doped nanoporous silica spheres (Eu:NPSs) through mediation of the 3-aminopropyltriethoxysilane adlayer. The ordered nanopores of Eu:NPS were preserved by the immobilization. The FA-immobilized Eu:NPSs showed the characteristic photoluminescence peak due to interactions between the FA molecules and Eu(3+) ions, and highly dispersed stability in phosphat...
